IMPROVEMENT IN CORN-STALK CUTTERS.

Specification forming part oi Letters Patent No. 124,401, dated March 5,1872.

To all whomit may concer-n:

Be it known that I, SAMUEL WALTERs, of Dallas City, in the county ofHancock and State of Illinois, have invented a new and valuableImprovement in Corn-Stalk Gutters, and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawingmaking a pa-rt of this specification, and to the letters and figures ofreference marked thereon.

Figure l ofthe drawing is a representation of a vertical longitudinalsection of my invention; Fig. 2 is a top-plan view of the same.

This invention has relation to corn-stalk cutters; and the noveltyconsists in the construction and arrangement of devices for giving avertical chopping motion to the knife, of devices for raising the knifeabove obstacles, and keeping it in a uniform position.

In the accompanying drawing illustrating this invention, A represents arectangular frame mounted on two driving-wheels, B B'. O designates aspur-Wheel secured to the rotating axle of the wheels B B', and turningwith it. D represents a shaft holding a slid- 'ing pinion, E, whichengages with the spurwheel O and a crank-arm, D', which is coupled to alever-arm, E', pivoted to one end of a rocking ba-r, F. G designates aframe hinged to the frame A. Secured to it is a bracket, H, to which therocking bar F is pivoted and -works on as on a fulcrum. The end of saidbar, opposite the arm E', is coupled to a link, I, which supports avertical rod, I'. The knife J is secured to the lower end of said rod ina horizontal transverse position, the cutting-edge below. The rod I'works through a guidingbracket, i, attached to and projecting from themiddle longitudinal bar of the frame A. The vertical chopping motion ofthe knife is caused through the medium of the pinion and gearwheel,acting through the intermediate devices referred to and described. Krepresents a clutch-arm pivoted to a backet, K', and designed for thepurpose of throwing the gearwheel and pinion into and out of gear. Lindicates a bell-crank pivoted underneath the inner end ofthe frame G.AIt is connected, by means of a rod, L1, to a foot-lever, L2, withinreach of the drivers foot, M being the drivers seat. By pressing thelever L2 forward the frame G may be raised so that the knife may passover obstacles. One arm of the bell-crank should be curved so as to workagainst the under side of the frame G with ease. N designates afriction-roller for keeping the knife in a steady, even position, andprevent it from being thrown out of place by obstacles. Said roller isjournaled to the end of a bent arm, N', extending back from the frame G,to which it is attached. O represents'a pressure-roller, arranged infront of the knife. It is journaled to a pair of arms, I?, hinged to theforward end of the frame A.

I claim as my invention- The frame G hinged to the frame A andsupporting the rocking-bar F, in combination with the bell-crank L, rodL1, and foot-lever L2, or other equivalent operating devices,substantially as specified.
